THlLL-COUPLING.

SPECIFICATION formingpart of Letters Patent No. 228,993, dated June 22,1880. Application filed February 16, 1880.

To all whom it may concern:

Be it known that I, ODILON (Music, of Springfield, county of Hampden,and State of Massachusetts, have invented new and useful Improvements inThill-Oouplings, which improvements are fully set forth in the annexedspecification and in the accompanying drawings.

My invention relates to thill-couplin gs which are constructed with aview to prevent their rattling; and it consists in adapting to anaxleclip of ordinary construction a thill iron or coupling constructedwith a wide oblong bolthole transversely through it, providing thereinsufficient room for said bolt for a surrounding elastic packing for itand for a pressureblock, and having a setscrew or screw-bolt operatingthrough one end of said oblong bolthole at right angles to said boltagainst said pressure-block, to cause the bolt to be tightly securedbetween said elastic packing and within said wide oblong bolt-hole.

In the drawings, which consist of three figures, Figure l is a sectionalview through the line a; m, Fig. 2. Fig. 2 is a side elevation, partlyin section, showing one thill-iron support removed. Fig, 3'is the boltwhich connects the thill-iron to the axle-clip.

A is the thill-iron provided with theoblong boltliole b. O is theaxle-clip, and c e are the thill-iron supports thereon. i is ascrew-bolt. o is a pressureblock. s s are sections of elastic packing,and tfis the connecting-bolt.

I construct the thill-iron A with the oblong bolt-hole b, as shown, andtit the screw-bolt '6 through one end of said bolt-hole, and fit intothe latter under the end of bolt 6 the pressureblock 0. Between theunder concave edge of block 0 and the lower end of 1 the oblong boltholeI) the bolt t passes transversely through;

but spaceis provided between thelatter-named parts and the sides of boltt for the interposition between thein 'of the elastic packing s s, lyingaround said bolt and extending over that portion of it which is withinthe bolthole I).

The axle-clip G is constructed of the usual form and is provided withthe thill-iron supports 0 e, pierced for bolt 15, which is securedtherein by a nut in the usual manner.

Thus when the above-named parts are placed, as shown, in the bolt-holeb, and bolt t is inserted through supports cc and through the bolt-holebetween the elastic pieces .8 8, said bolt will not come in contact withany part of the thill-iron A, and by screwing bolt 2' down against block0 bolt 8 becomes tightly compressed between the sides of said elasticpacking, and all rattling of parts is prevented.

Myiinproved thill-iron possesses advantages over other thill-irons inwhich elastic packing is interposed between the outer end of thethill-iron and the axle-clip in that the elastic packing is so protectedby being inclosed within the bolt-hole and between the sides of supports6 c that it is much more durable and all wear thereof can be taken up byscrewing down bolt 6.

What I claiin'as my invention is- The combination, with the axle-clip 0,provided with the supports 6 e and with bolt 15, of the thill-iron A,provided with the oblong bolthole I) and the screw-bolt t, thepressureblock 0, and the elastic packing s s, substantially as and forthe purpose set forth.

ODILON GRISE.
